Hello I have 1h40 to make a stopover in Dallas on a flight Paris los Angeles is that enough?  Passages in Customs and security included.

We had 50 Minutes. We asked one of the official stuff and we paid for his help. He brought us within 10 Minutes to the gate. Just perfect. We paid 50 Dollar for this service. Without his help the time would have been to short, because of very busy sequrity check. We passed approx 250 People in front of us.

Depends on when your flight arrives and how busy customs is. But should be enough time.

What is this service?
